Forbes CommunityVoice™ allows professional fee-based membership groups ("communities") to connect directly with the Forbes audience by enabling them to create content – and participate in the conversation – on the Forbes digital publishing platform. Each topic-based CommunityVoice™ is produced and managed by the group.

Opinions expressed within Forbes CommunityVoice™ are those of the participating individuals.

No two people are bound to be exactly alike on a team. Everyone differs in terms of personality, mindset, productivity and more. This type of diversity is what makes a team successful. Each person plays a different role and therefore contributes something different that will help the team accomplish its ultimate goal. A team made of up people who are too similar is not likely to be very successful.

We asked members of Forbes Coaches Council for suggestions on the kind of person that no team should be without. Which of these types of people are on your team and what kinds of people would complete your team?

1. The Swiss Army Knife

The founding team of a startup needs a Swiss army knife, someone who specializes in being a generalist. The generalist allows the founder to think strategically while knowing that the more operational tasks are being performed. - Steven Maranville, Maranville Enterprises

2. The Idea Person

It's easy to get caught up in everyday tasks and execution and dismiss the "idea people" on your team. These team members frequently start their sentences with "What if we did it this way ..." or, "How about we try ..." Instead of dismissing their ideas as pie in the sky, hear them out and ask how their way may actually drive execution even better. By giving them a forum to speak, you will likely find that their ideas will improve efficiency and performance. - Loren Margolis, Training & Leadership Success LLC

3. The Doer

Ideas are a dime a dozen, and most ideas never even get off the ground for two reasons: follow up and execution. That is when the "the doer" type proves his/her value. "The doer" with his/her relentless follow-up and implementation will be the driving force to plan, follow up, and implement. This type of team member can have an immense impact on innovation and profitability of a given organization. - Kamyar Shah, World Consulting Group

4. The Thinker

A successful team is a well-rounded one with complementary personality traits. One personality that is commonly overlooked is the "thinker." This person is usually reserved and likes to consider the issue at hand before speaking. While others are jumping into action with half-baked ideas, the thinker will have assessed potential risks to arrive at the best possible path forward. - Erin Urban, UPPSolutions, LLC

Most ideas never get off the ground because they simply remain ideas. Teams may have visionaries and managers, but if they do not have someone who is relentlessly focused on diving into the details and logistics of an idea or project, the project will never see completion, and the world will miss out on the fulfillment of missions, plans and exciting breakthroughs that die before implementation. - Billy Williams, Archegos

6. The High Driver

Every team needs an individual who has a high-driver personality. This is the personality type that focuses on results and has the ego strength to get things done. However, the person's personality structure needs to be balanced out with other types of personalities. A team with only high drivers would devolve into constant arguments about right and wrong. Ensure your team is balanced for success. - Gregory Stebbins, Ed.D., PeopleSavvy

7. The Overachiever

While the team may groan, overachievers provide momentum to every team. Positive peer pressure comes from diligence and the pursuit of excellence. If you have a stand-out employee, encourage them privately and publicly. Also, watch for burnout. Overachievers are often missing self-awareness and personal boundaries. Encourage your team to do their best and remind everyone they're in it together. - Heather Murphy, Authentically: Business & Life Solutions

8. The One Who Won't Give Up

Sometimes when things go wrong on a project or with a client, we get this urge to quit, simply sign out, erase the problem from our life and move on to the next project, client, or start looking for more leads. The problem might go away for the time being, but your team's inability to deal with such challenges still remain at large. Quit once and you'll do it again without noticing. - Nader Mowlaee, Career Recovery Academy

9. The Chameleon

There is nothing better than having a team member who, like a chameleon, can adapt to any situation, personality or challenge. This driven, flexible and yet empathetic person can lead, problem solve, cheerlead, support and step into any gap that may arise. Chameleons are born to adapt to their environment and will become whatever you need to meet your goals, so focus on having one on your team. - Laura DeCarlo, Career Directors International

10. The Accessible And Responsive One

One bonding question that our brain asks is, "Are you there for me?" A - Are you accessible to me?; R - Are you responsive to me?; E - Are you emotionally engaged with me? Even though you don't agree with me, can you understand my pain or concerns, can you still respond to me, and can you stay engaged? When a person is able to be A.R.E., they create an emotional connection the team needs to ensure success. - Lola Gershfeld, PsyD, Level Five Executive, Inc.

11. The Listener

Every team needs someone who is trained to hear between the lines and who knows the team perhaps better than the team knows itself. Without an understanding of all the people on the team and a desire to really listen to what is wanted and needed, the team will likely fail. That level of listening usually comes with someone who has managed their ego. - Lori Darley, Conscious Leaders LLC

12. The Contrarian

The most needed type of team member is the person who always tries to uncover why what is being proposed will not work. The advantage is that it develops collective intelligence. They prompt empathy rather than defensive or aggressive responses. It ensures diversity as there will be always a different perspective, and it stretches the team to find a balance between opposites. - Valerio Pascotto, IGEOS

13. The Giver

Organizational psychologist Adam Grant does a wonderful TED Talk on givers, takers and matchers. His research shows that the output and performance of teams increases when one person is a strong giver. Givers, however, need to be nurtured as they can burn out and overcommit due to their interest in helping and serving others. Unleash your givers to maximize your team's success! - Evan Roth, Roth Consultancy International, LLC.
